Two things:
- remove the buffer argument from VG_(DebugInfo_sect_kind)
- allocate AddrInfo::SectKind::objname dynamically

* VG_(find_seginfo): incrementally rearrange the DebugInfo list, like
most of the other list-searching functions do.
* rename all VG_(*seginfo*) functions exported from m_debuginfo to
VG_(*DebugInfo*). "seginfo" was a historical name which was mostly
but not completely, done away with some time back.

that are memory offsets) with PtrdiffT; OffT should only be used for file
sizes and offsets.
Change Off64T from a ULong to a Long, as it should be. Replace some uses
of ULong in the address space manager with Off64T to match.
Also add a comment explaining the meanings of the basic types like Addr,
OffT, SizeT, etc.
Also fix the prototype for VG_(pread) -- the last arg is an OffT, not an
Int.

relatively minor extensions to m_debuginfo, a major overhaul of
m_debuginfo/readdwarf3.c to get its space usage under control, and
changes throughout the system to enable heap-use profiling.

When instrumentation mode is switched off, we want to fully
reset callgrinds internal execution state, which includes
the shadow call stack and function stack for context generation.
The latter was not completely reset before.
The bug showed up when switching the instrumentation mode on for
the second time, leading to
Callgrind: callstack.c:211 (vgCallgrind_push_call_stack):
Assertion 'current_entry->cxt != 0' failed.
This commit also improves debug output a little bit.

Bug description: Very similar to cachegrind, callgrind stores
metainformation per guest instruction; this meta information is
given when calling into the simulator. In contrast to cachegrind,
callgrind keeps this info when the source is discarded, and checks
on retranslation whether the same meta info is generated.
This check sometimes fails: E.g. for rep x86 instructions, 2 simulator
calls
are usually generated for one x86 instruction (the instruction fetch and
a
data access), thus overwriting the data_size meta information for one
x86
instruction first with 0, and afterwards e.g. with 1. The check on
retranslation
fails because of this. The fix is to only write/check data_size values
>0.
